！：。Conventionally, 18Cr-8 was used as the material for wristwatch exterior parts.
The main point is 7T, which is plated on austenitic stainless steel such as Ni, nickel silver, or brass, but due to the thinning of wristwatches in recent years and the demand for quality in the market, the above materials are being used. Other N1-based good-resistant materials, such as Hastelloy and Inconel, are also used. Although these N1-base alloys have achieved the goal of improving corrosion resistance, they are extremely difficult to add soil to, especially when cold carpeting is used in all processing methods for exterior parts.

たものである。The present invention maintains the immediate corrosion resistance of the N1-based alloy while achieving the workability necessary for exterior parts, and uses a special combination of highly corrosion-resistant elements CO + Or + MO in the special KNivf-Pace. This goal was achieved through ratios.

４０俤である。Cott is the element that contributes the most to improving corrosion resistance in this base metal, and the blending ratio with N1 is particularly important for maintaining corrosion resistance in this alloy. That is, it is desirable to mix N1 and CO at a ratio of α8 to 1:1.2, and the base N1 content and corrosion resistance are 950%.

限足する。Cr14 is an element that improves the strength and maintains the corrosion resistance of base metal, and its effects are obvious, but as the amount of addition increases, material processing becomes difficult, so it is limited to #'j25. Add a limit.

A wire rod of φ[lL6■ was processed through the same stretching process as the previous one, and further, in order to produce a mesh band for wristwatches, the Hastelloy C1j was sintered at a high temperature of 1100 to 1750°C in the 0 stretching process and stretched repeatedly with a force of 1. However, in the case of uninvented alloys, the number of annealing was small at 900 to 1000°C, and the processing rate was high, so that wire rods with wire size L6 could be processed in a short process. When the rL hole watch band obtained by 596 was immersed in saline solution and artificial sweat for one week, the alloy made from the alloy of the present invention showed no rusting at all, similar to the Steroid C band.
